jsPerf.app is an online JavaScript performance benchmark test runner & jsperf.com mirror. It is a complete rewrite in homage to the once excellent jsperf.com now with hopefully a more modern & maintainable codebase.
jsperf.com URLs are mirrored at the same path, e.g:
https://jsperf.com/negative-modulo/2
Can be accessed at:
https://jsperf.app/negative-modulo/2
<ul id="my_list">
</ul>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js">
</script>
<script>
$(function() {
var i = 0,
$ul = $('#my_list'),
$li = $('<li />').html('list item');
while (i < 100) {
$ul.append($li.clone());
i++;
}
});
function empty(element) {
var i;
for (i = element.childNodes.length - 1; i >= 0; i--)
element.removeChild(element.childNodes(i));
}
function empty2(element) {
while (element.childNodes.length > 0)
element.removeChild(element.childNodes(0));
}
function empty3(element) {
var child;
while (child = element.lastChild) {
element.removeChild(child);
}
}
function empty4(element) {
while (element.lastChild) {
element.removeChild(element.lastChild);
}
}
